The 2018 Mercedes-Benz Trucks GLE63 AMG blends high-performance AMG character with the added weight, stance, and road presence of a modern luxury SUV. On a vehicle like this, tire selection is tied closely to preserving the intended balance between sharp handling, stability, and visual proportion. Fitment centers on staggered radial sizes, with 265-section tires used at the front and 295-section tires at the rear, and wheel diameter matters because both 20-inch and 21-inch setups are in play. That makes this page less about broad experimentation and more about confirming the exact front and rear combination already on the vehicle before comparing available tire choices.
Which Tire Size Is Right for The 2018 Mercedes-Benz Trucks GLE63 AMG
The 2018 Mercedes-Benz Trucks GLE63 AMG uses four primary tire sizes because fitment is split by axle position and wheel diameter. Front tires are either 265/45R20 or 265/40R21, while rear tires are either 295/40R20 or 295/35R21, so the first step is confirming whether the vehicle is on 20-inch or 21-inch wheels and then matching the correct front and rear pair.
The size 265/40R21 indicates a 265-millimeter section width, a 40-series aspect ratio, radial construction, and fitment on a 21-inch rim. On the 2018 Mercedes-Benz Trucks GLE63 AMG, this is a front tire size used as part of the staggered 21-inch setup, so it works in conjunction with a wider rear tire rather than as a universal four-corner size. Its role is to maintain the proper front fitment for that wheel package. Buyers should confirm both axle position and wheel diameter before selecting it.
The size 265/45R20 uses the same 265-millimeter nominal width as the 21-inch front option, but it is built around a 45-series profile and a 20-inch rim. For the 2018 Mercedes-Benz Trucks GLE63 AMG, this size belongs on the front axle when the vehicle is equipped with the 20-inch staggered arrangement. That distinction matters because the matching rear tire changes with it. This size should be chosen only after verifying that the vehicle is using the 20-inch front and rear wheel set.
The size 295/35R21 designates a 295-millimeter-wide radial tire with a 35-series profile for a 21-inch rim. On the 2018 Mercedes-Benz Trucks GLE63 AMG, it serves as the rear tire in the 21-inch staggered package, giving the vehicle its wider rear fitment relative to the front axle. This is not a substitute for the front tire size, even though both belong to the same vehicle. Selecting it starts with confirming the rear position and making sure the vehicle is actually on the 21-inch wheel setup.
The size 295/40R20 means a 295-millimeter section width, a 40-series aspect ratio, radial construction, and a 20-inch rim diameter. For the 2018 Mercedes-Benz Trucks GLE63 AMG, this is the rear size in the 20-inch staggered arrangement, paired with a narrower 265/45R20 front tire. Available product choice in this size includes a Blackwall Nitto NT555 G2, which gives buyers at least one performance-oriented option within the correct rear fitment. It should be evaluated as part of the full 20-inch front-and-rear combination rather than by rear size alone.
Fitment on the 2018 Mercedes-Benz Trucks GLE63 AMG is straightforward once axle position is identified, because the front and rear use different tire sizes. Checking whether the vehicle is on 20-inch or 21-inch wheels is equally important, since each axle has two possible sizes tied to wheel diameter.

2018 Mercedes-Benz Trucks GLE63 AMG 4Matic Front
The 2018 Mercedes-Benz Trucks GLE63 AMG 4Matic Front uses a 265-section radial tire, with the exact size determined by whether the vehicle has 20-inch or 21-inch wheels. Tire selection here starts with confirming wheel diameter so the front tire remains properly matched to the rear staggered setup.
The 2018 Mercedes-Benz Trucks GLE63 AMG 4Matic Rear uses a wider 295-section radial tire, again split between 20-inch and 21-inch wheel packages. Rear tire choice should stay aligned with the wheel size already on the vehicle and with the corresponding front fitment rather than treating the rear size as a stand-alone swap.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2018 Mercedes-Benz Trucks GLE63 AMG Tires for Sale
Available product selection centers on the 295/40R20 rear size, with a radial Blackwall option from Nitto in the NT555 G2 series. For this vehicle, the main comparison point is staying with the correct staggered size and wheel-diameter combination.
Owners of a 2018 Mercedes-Benz Trucks GLE63 AMG usually need to confirm front versus rear sizing, 20-inch versus 21-inch wheels, and how available tire choices affect a staggered setup. These FAQs focus on fitment, product selection, appearance, and road-use checks.
Tire Size & Fitment
What tire size fits a 2018 Mercedes-Benz Trucks GLE63 AMG?
The 2018 Mercedes-Benz Trucks GLE63 AMG uses a staggered radial setup rather than one single size at all four corners. Front fitment is either 265/45R20 or 265/40R21, while rear fitment is either 295/40R20 or 295/35R21.
The key is identifying both axle position and wheel diameter before choosing a tire. A front size should be paired with the matching rear size for the same 20-inch or 21-inch package, and a rear size should not be selected as though it applies universally across the vehicle.
What size rim does a 2018 Mercedes-Benz Trucks GLE63 AMG use?
The 2018 Mercedes-Benz Trucks GLE63 AMG uses either 20-inch or 21-inch rims, depending on the tire package on the vehicle. The 20-inch setup uses 265/45R20 front and 295/40R20 rear, while the 21-inch setup uses 265/40R21 front and 295/35R21 rear.
Wheel diameter should be confirmed before anything else because it determines the entire front-and-rear tire combination. A quick check of the current sidewall markings and the wheel itself helps prevent mixing a 20-inch tire into a 21-inch setup or vice versa.
Why does the 2018 Mercedes-Benz Trucks GLE63 AMG have more than one tire size?
This vehicle has more than one tire size because it uses staggered fitment and more than one wheel-diameter package. The front axle uses 265-section tires, the rear uses wider 295-section tires, and each axle has one size for a 20-inch setup and another for a 21-inch setup.
That means the correct choice is not just about matching the year and model. The buyer also needs to confirm front or rear position and verify whether the vehicle is equipped with 20-inch or 21-inch wheels before comparing tire options.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Mercedes-Benz Trucks GLE63 AMG?
Start with the exact fitment already on the vehicle: front versus rear and 20-inch versus 21-inch wheel diameter. The 2018 Mercedes-Benz Trucks GLE63 AMG does not use one universal tire size, so correct selection depends on matching the proper staggered combination.
After size is confirmed, compare the available tire's construction, sidewall style, series, and any useful product details such as weight or load specification where offered. On a performance SUV, keeping the front and rear setup properly paired matters as much as choosing the individual tire itself.
What sidewall styles are available for 2018 Mercedes-Benz Trucks GLE63 AMG tires?
Available sidewall style depends on the exact size being considered. In the 295/40R20 rear fitment, the currently available product uses a Blackwall sidewall, which suits a modern, understated performance appearance on the 2018 Mercedes-Benz Trucks GLE63 AMG.
Sidewall style is mostly an appearance decision once size and wheel diameter are correct, but it still matters on a vehicle with a strong visual stance. Buyers replacing only one axle should also think about how the front and rear tires will look together once mounted.
What brands offer tires for the 2018 Mercedes-Benz Trucks GLE63 AMG?
Current product availability for this fitment includes Nitto, specifically in the 295/40R20 rear size. The available tire in that size is part of the Nitto NT555 G2 series and uses radial construction with a Blackwall sidewall.
Brand comparison only becomes useful after confirming the exact axle position and wheel diameter, since this vehicle uses multiple sizes. On a staggered setup, checking the full front-and-rear plan helps avoid choosing a rear tire first and discovering the matching front strategy needs separate review.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Mercedes-Benz Trucks GLE63 AMG restoration or appearance refresh?
Yes. Even on a modern performance SUV, the correct tire size matters because the 2018 Mercedes-Benz Trucks GLE63 AMG relies on a staggered front-and-rear setup and the proportions are part of the vehicle's overall look. The wrong aspect ratio or rim diameter can change that presentation quickly.
An appearance-focused replacement should begin by matching the existing 20-inch or 21-inch package and keeping the proper front 265-section and rear 295-section relationship intact. That approach preserves the intended stance more effectively than choosing tires by width alone.
How does tire construction affect the appearance of a restored 2018 Mercedes-Benz Trucks GLE63 AMG?
For the 2018 Mercedes-Benz Trucks GLE63 AMG, tire construction is radial throughout the primary fitments, so the visual question is less about bias-ply versus radial and more about maintaining the correct modern sidewall profile. The 20-inch and 21-inch packages each create a different overall presentation.
A clean, vehicle-appropriate look usually comes from staying with the correct front-and-rear size pair and choosing a sidewall treatment that matches the owner's goals. Blackwall styling, for example, keeps the appearance restrained and performance-oriented without drawing attention away from the wheel design.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Mercedes-Benz Trucks GLE63 AMG?
Yes. Any change to wheel diameter, wheel width, offset, suspension height, or fender clearance can affect tire fitment on a 2018 Mercedes-Benz Trucks GLE63 AMG. That matters even more on this vehicle because the front and rear sizes are already staggered from the factory-style setup.
A modified vehicle should be checked carefully before replacement tires are chosen. Verifying the actual wheel dimensions on the vehicle, checking clearance at full steering lock, and confirming space around the rear suspension and fender area can prevent selecting a size that only appears correct on paper.
What should I inspect before driving a 2018 Mercedes-Benz Trucks GLE63 AMG on new tires?
Before road use, inspect the wheel and tire combination for correct front and rear placement, proper inflation, secure valve stems, and any obvious mounting issues. It is also wise to make sure the tire sizes match the vehicle's 20-inch or 21-inch package rather than mixing components from two different setups.
A short visual check around the sidewalls and tread after installation helps catch problems early. On a high-performance SUV, it also makes sense to look for clearance around suspension components and confirm that the steering turns freely without rubbing before heading into regular road use.
How often should tires on a 2018 Mercedes-Benz Trucks GLE63 AMG be inspected?
Tires on a 2018 Mercedes-Benz Trucks GLE63 AMG should be inspected regularly, especially before longer drives and after any period of limited use. Check for uneven wear, cuts, bulges, sidewall damage, embedded objects, and gradual air loss, since performance-oriented fitments can be sensitive to condition changes.
Routine inspections are also useful for confirming that the staggered setup remains properly matched and that no wheel damage has developed. A vehicle driven seasonally or stored for stretches should have tire condition reviewed more carefully, since age and storage environment can matter as much as mileage.
